Hi, I am new to scanning and have a new GRE PSR-300. I have updated the 800mhz table and it is working great. I live in Davis County. I entered the control frequencies based on the Davis County entries in the database. I see that there are other control channels for other counties. Because its simulcast I can hear SLCounty and Weber County traffic. Do I need to enter control frequencies for Weber and Salt Lake Counties as well. I also see entries for sites on some of the peaks close to my house. Should they be used as well or do I just need the single control freq and its alternates ???
